7 Claims. (Cl. 229-23) This invention relates to a carton for contain ing fruit, bottled goods and other articles.

A feature of the invention is the provision of a carton having a body, a hinged lid, handle structures for lifting and carrying the carton, and sealing arrangements, all presented by the cutting, folding and securing of corrugated .board, flber board, or like stiilly flexible and strong materlal.

Another feature of the invention is the provision of a carton having a double-bottom thickness and having a body portion formed with a handle structure constituting reinforcement at the upper edge of the body, and provided with a hinged cover which overlaps the reinforcement, and fits in abutment with parts of the body when p in closed position, for easy sealing.

, A further feature of the invention is the provision of a carton of the aforesaid type, together with stiffening means for strength of the body walls and cover, and providing for a full-height receptacle during packing and an overlap during the closing and sealing.

With these and other features as objects in view. an illustrative form of drawing is shown in the accompanying drawing.

. Figure 11 is a perspective view of an insert waterproof member. s

The basic carton, shown in Figs. 1 and 2, has

- top and bottom walls HI, I I, front and back walls i2, I 3, and the end structures provided each by an end wall It, the folded hand grips l5, and the overlapping and secured flanges l6, l1, It. The top wall ill has integral flanges l9, 20,2l, 22 and sit'lons and secured so that they correspond in cross-section to the free edges of the front wall I! and to the flanges 16, I1, and abut there- 'against when the carton is closed (Fig. l). A

score line 25 at the plane of the top edges of the flanges I1 provides a hinge about which the cover is swung for opening (Fig. 2) or closing. In closed position, the flanges of the cover overlap the hand grips l5 and provide strong and tight end closures; the back wall is integral; and a sealing tape 28 is applied (Fig. 1) to the front wall l2 and the cover flange in their co-planar and abutting position, for sealing this part of the carton and securing it in closed position.

It will be observed that the top, bottom, front and back walls are smooth outside, so that the fllled cartons may be slid easily over a floor or one another, and so that a carton in one stack may -be slid out without disturbing contacting cartons in adjacent stacks. These parts, and also the inner faces of the end walls It, are smooth inside, and thereby avoid damage to sensitiveskinned fruits.

The body and cover of the illustrative carton are formed from two blanks, as shown by the layouts in Figs. 3 and 5.

The blank of Fig. 3 is cut from a single sheet of suitable material such as corrugated board; and has the flange I9, the top or cover wall M, the flange 20, the rear wall l3, a bottom wall II, and the front wall l2 arranged in that order, and separated from one another by the score line 25 for forming the cover hinge and by other score lines 30 parallel to one another and used to facilitate accurate folding. Each of these areas has integral tabs joined therewith across score lines, to provide the tabs 23 on the flange IS; the flanges 2|, 22 on the top wall [0; the

tabs 24 on the flange 20; the flanges H onthe back wall IS; the flanges I 8 on the bottom wall H; and the flanges It on the front wall l2. By preference, the front and back walls I 2', l3 are of the same height, and the flanges I9, 20 are of the same height; so that the abutment occurs at a common horizontal plane, and the combined height of front wall 12 and flange I9 is equal to the combined height of the rear wall l3 and flange 20.

The blank of Fig. 5 is formed from a single sheet of like material, with parallel edges, and p rovides in succession the inner fold-flange l5, the outer fold flange li the end wall l4, the bottom wall II, the end wall 14, the outer foldflange It, and theinner fold flange l5. Score bottom wall H of the blank of Fig. 3, and determines the correspondin inside dimension of the basic carton. The other dimension of the bottom wall I I determines the inside length of the basic carton; and the corresponding dimension of the bottom wall H is determined by the thickness of the selected material, so that the flanges i1, i8 will flt tightly against the outer faces of the end walls ll.

These blanks can be out and scored by existing box-factory equipment without difliculty; and can be shipped in the flat to a fruit packer, for example, who employs standard stapling ma chines to secure the assembly.

The assembly is performed by bending the blanks at the score lines provided, to approximately the forms indicated in Figs. 4 and 6. The hand-grip is formed by turning the inner part 55* into flat engagement with the outer part I5 and then folding the two down flat against. the outer face of the corresponding end wall 14, so that (Figs. 2 and 6) the cut edge is located within the triple thickness thus formed, and the folds at the top and bottom of the hand grip portions ll, l5 are smooth. The folded blank of Fig. 6 is then inserted in the blank of Fig. 4, and the parts are stitched, together by the stapling machine, into the form shown in Fig. 2. In this operation. the two bottom walls H, H lie one on the other, to provide a double bottom thickness, and the front and back walls l2, ii are fitted against the edges of the bottom wall ii to give great strength and rigidity to the bottom. The flanges l6, l1 are fitted over and stitched to the end walls H and also over and stitched to the folded parts I5, i5 which provide the hand grip is, to prevent unwinding thereof. The flanges i8 iit closely against the central parts of the end walls H, at their bottom; and are stitched thereto and to the flanges l6, H. The stitching of the tabs 23, 2 to the flanges 2|, 22, to form the cover, may be accomplished before or after the stitching of the body, as may be more convenient.

The assembled carton (Fig. 2) is easily to load and close: and can be sealed against opening or loss of contents by a single length of gummed tape 28 (Fig.1). This basic container, with its doubled bottom, smooth internal surfaces, and great end strength, with convenient and natural position of smoothly finished hand grips, is satis factory for most employments. Sometimes, a particular commodity requires a higher front wall and a greater resistance to damage if dropped upon a corner. This can be attained with the same basic container by introducing a body liner and cover stiffener.

The blank in Fig. 7 is formed from a single sheet of like material, of rectangular shape, having the longer walls 40, ll and the shorter walls 42, 43, with the securing flange 44; separated by the scored fold lines 45. This is folded and stitched as shown in Fig. 8 to form a sleeve liner of rectangular section; and telescoped into the body of the basic carton, as shown in Fig. 10, and thus provides inner front and back walls of the entire inside height of the carton, with an over-lap for the flange 19 of the cover, and at the hinge line 25, thereby further strengthening I the structure.

The blank in Fig. 9 is formed from a single rectangular sheet of like material, with a central area 50 fitting closely inside the flanges I9, 20, M, 22 of the cover, and havin also the integral flanges 51, 52 separated by scored fold lines 53. This is tucked into the cover (Fig. 10) and stitched into position. It will be noted that the doubled and tripled end flange construction 2i-lfl--I3-5'2 and 22-l4 |353 of the cover flts tightly against the quadrupled thickness provided at the ends of the body by the end walls M, the flanges l5, l5, and the liner end walls 52 or 53; so that great rigidity is produced at these points, and extended across the entire cover by the doubling effect of top walls ill, 50. Hence, when closed and sealed, the package is strong; and when open it holds a full load of such products as beans, grapes, currents, etc.

It will be noted that the assembled container is easy to pack, seal, and handle: and that it is easily opened when so desired. Before splitting the sealing tape along the abutment line, undetectable pilfering is diflicult or impossible. Also, the double bottom of the basic container,-and the doubled walls of the reinforced container, adapt these to uses with products which may give off liquids; and to uses where the package may stand in water, as when placed upon a wet shipping platform: in either case, the liquid may soften and reduce the strength of the layer which it encounters, but does not easily or generally pass to contact with the other layer.

The several parts may be made of boards of different weights or compositions. Thus the blank of Fig. 5 may be of solid fiber board, and that of Fig. 3 of double-faced corrugated board.

The board liners of corrugated board may be of sized stock for water repellence.

The same blanks may also be used, in the same way, with the intercalation of a sheet of waterproof stock between the parts, to improve the resistance to internal or external wetting. Thus,

a sheet of resin-sized paper, asphalt-coated paper, waxed paper, etc., may be employed. In Fig. 11, such a sheet is shown as folded to provide a thin central field 60 which overlies the total area of the outside bottom part I i and has upstanding walls GI, 62, of height corresponding to that of the flanges l8 and useful to position the sheet during assembly. The specific form of Fig. 11 also has walls 63, 64, and the corners are formed by diagonal folding to provide the wings wherewith a waterproof tray of corresponding wall height is obtained, for inclusion in the container shown in Fig. 10 during its assembly.

It is obvious that the illustrated forms are not restrictive, and that the invention may be employed in many ways within the scope of the appended claims.
